초록 ▼

A method for restriping a striped disk array in a computer system without requiring the removal of the system from normal operation provides an efficient method to expand the disk array and incorporate the new storage into the striping scheme. When the operating system is not requesting access to the hard disk subsystem, the data is repositioned. The data on the array need not be backed-up onto alternate media before the array is expanded. Once new storage space is installed, the data is repositioned from disk to disk under the control of a disk controller until a stripe of the new array is expanded. Pointers stored in non-volatile memory maintain the location of the next free location and the next data block to be repositioned. The pointers are also used by the disk controller to locate the files during the array expansion process. The process is repeated until all of the data is relocated in the expanded array. After the relocation is complete, empty storage at the end of each disk remains. Once a new driver is installed to properly report the new volume to the operating system, the controller reports this new space as a separate volume of available memory storage to the operating system.

A method of expanding a striped hard disk array for a computer system during computer system operation, said hard disk array controlled by a hard disk controller which reports to a computer operating system an original data storage capacity of the array when the array is in a first fully operational configuration and which receives requests for access to the array from said operating system, the first fully operational configuration of the array having at least two original physical disk drives with data striped across the disks, wherein the corresponding stripe for each disk in the array is one row, the method comprising the steps of: (a) adding at least one added physical disk drive to the two original disk drives in the disk array to create an upgraded data storage capacity in a second fully operational configuration of the array, the second fully operational configuration comprising the original disk drives and the added disk drive, said upgraded storage capacity being an increase from said original data storage capacity; (b) selecting a row in the disk array for expansion to incorporate a portion of the added disk; (c) waiting for a predetermined delay period during which the operating system issues no requests for access to the disk array; (d) preventing access by the operating system to the disk array once the predetermined period expires; (e) selecting a data block in the original disk drives in the disk array for expansion; (f) relocating said data block to fill a storage location created in the selected row by the addition of the added disk drive; (g) identifying with a first indicator the next free location in the array to be expanded; (h) identifying with a second indicator the next data block in the array to be relocated; (i) permitting the operating system to access the hard disk array; and (j) reporting to the operating system said upgraded storage capacity of the second fully operational configuration of the array.
